Search Results: letting me know that he has a girlfriend

So, I'm trying to figure out what happened

But based on this experience I do know a lot more about what I want, don't want and what not to put up with

My ex met my mom, sister and neice, but she didn't bother letting me see her family or even male best friend whose name she mentioned a lot on our dates, even when nudged or asked. She is a gym rat and so is he, they're coworkers at the same college fitness center. They knew each other for 4-5 months prior to our relationship so I know she has much longer friendships. She would tell me about his athletic feats and his "amazing but gross muscles", unsolicited. This specifically was on a date just before meeting my family. I thought I would playfully express honest emotions of jealousy or discomfort to such a topic at that time by saying, "hey I can do that too." But she kind of threw it back in my face as me being a turn off and insecure. She said "You're not the only guy in the world", which registered to me as a red flag, but I didn't want to believe it and took her to meet my family anyway. [Additional question: Was she right? I have read that expressing jealousy is unattractive when your girlfriend reveals her male best friend. But at the same time, when our relationship started, she explicity told me that she had no best friend, but she wished she had one.]

Anyway strangely enough, she has him move into her house with her because his visa ran out. He has a girlfriend and she told me she'd never cheat but I'd still never met him and she doesn't offer. I ask to help move and she says he doesn't have much to move. The school semester starts and she says she'll be busy. I try to give her space. I text something almost every day and call maybe 2 times a week as she ghosts me for three weeks with him in the house. Of those calls, the first one was returned after the first week. But after the third week she dumped me on snapchat, and refused to answer the phone when I called that day. She said the word love creeped her out
